Ms. Pac Man from Namco is first out the gate with iOS 4.1 Game Center support, but there are plenty more to come. We'll update this post -- and we'll keep updating our new Game Center games tracker in the iPhone Forums -- as new ones arrive, but here's a first look at Leaderboards and Achievements... after the break!

For more new features, see our iOS 4.1 walkthrough.
